<h3>JANIG Takes to the Water</h3>
<p>A figure dove to meet Rick. He angled away, fighting the impulse to
breathe, keeping the compressed air moving out of his lungs. The figure
angled with him, then suddenly sheered off. Rick shot past and the
figure followed.</p>
<p>These new frogmen were diving in midseason suits. He was aware of nearly
a dozen of them. He didn't count them; with his terrible need for oxygen
he didn't care that much.</p>
<p>He knew he would make it. He had to! But where was Scotty?</p>
<p>Rick shot to the surface, went right through it, his impetus carrying
him into the blessed air. He gulped a great lungful before he fell back
with a splash, and as he hit water his fins were flailing, to carry him
toward the hastily glimpsed shore.</p>
<p>A masked figure surfaced beside him and called, "Take it easy!"</p>
<p>He only moved faster. The frogman caught him easily, because the power
was gone from his leg strokes now. But he had enough strength to fight.
He reached for the frogman's face plate, and a strong arm pushed him
back.</p>
<p>A voice penetrated his consciousness. "Stop it, Rick, or I'll have to
let you have one."</p>
<p>The frogman knew his name! He hesitated, fist pulled back to throw the
best punch he had left, and the new frogman back-pedaled.</p>
<p>"Hold it," the frogman called, and lifted his face mask.</p>
<p>Rick stopped moving, staring numbly.</p>
<p>Jimmy Kelly! Lieutenant Kelly!</p>
<p>"I'll tow you to the boat," the lieutenant called. "Relax."</p>
<p>Rick obeyed, head spinning. He was a little groggy, and he couldn't make
sense out of things. How had Kelly got here?</p>
<p>And Scotty! Where was Scotty? He started struggling again, calling his
friend's name.</p>
<p>"He's all right," Kelly said urgently. "Relax, Rick!"</p>
<p>Rick caught the words, and they penetrated. How did Kelly know Scotty
was all right? But the lieutenant had spoken with authority, so he
relaxed.</p>
<p>Kelly towed him to the landing stage of the ship Rick had seen, a
destroyer escort. Willing hands lifted him from the water. He slumped
down on the edge of the stage, shaking his head to clear it while Navy
frogmen stripped his aqualung harness from him and pulled the mask from
his face.</p>
<p>A voice said, "Drink this."</p>
<p>A mug of steaming black coffee was thrust into his hand and he sipped,
grateful for the spreading warmth it brought.</p>
<p>Suddenly he started again. "Scotty! Where is he?"</p>
<p>"Up here, Rick, with me."</p>
<p>He looked up, and his eyes focused again—on Tony and Zircon!</p>
<p>A motor whaleboat drew up to the landing stage, and two husky frogmen
handed up a suited figure. "Here's one, Lieutenant," a frogman called.</p>
<p>"All right, Danny. Where's the other?"</p>
<p>"Heading for the reef at top speed. Jonesy's after him."</p>
<p>"Go help Jonesy haul him in."</p>
<p>"Yes, Sir." The motor whaleboat veered off and sped toward shore.</p>
<p>A frogman surfaced almost at Rick's feet. He instinctively drew back,
and the frogman gripped the edge of the stage, spat out his mouthpiece,
and pulled up his mask with the other hand.</p>
<p>Rick found himself looking at Steve Ames! What was he doing here?</p>
<p>"Where's the brass ball?" Steve asked.</p>
<p>"I don't know."</p>
<p>With an effort Rick pulled his scattered wits together. His mind began
to work again. Obviously, through some miracle Steve and Zircon had
arrived on a Navy ship with Jimmy Kelly and a detachment of Navy
frogmen.</p>
<p>Scotty called from on deck. "It's at the octopus cave, Steve. I saw one
of the frogmen drop it there."</p>
<p>Steve hauled himself out to the landing stage. He grinned at Rick.
"Feeling better?"</p>
<p>"Much," Rick said. He was beginning to feel nearly human again.</p>
<p>"Let's go on deck. I want to find out about this octopus cave."</p>
<p>Rick stood up, and was surprised to find that he didn't wobble. He
followed Steve up the ladder to the deck and found Scotty seated on a
canvas stool, sipping coffee.</p>
<p>Zircon asked anxiously, "Are you all right, Rick?"</p>
<p>Tony said, "Here's the doctor for a look at you."</p>
<p>A young Navy officer joined them and motioned Rick to a canvas stool. He
applied a stethoscope and listened, then grunted his satisfaction. "He
seems all right. Pulse a little fast, but that's to be expected. You had
a slight dose of oxygen starvation. Feel better now?"</p>
<p>Rick nodded. He was beginning to feel wonderful. They were out of it,
and with whole skins.</p>
<p>Scotty grinned sheepishly. "I abandoned you. I had to, because I ran
completely out of air. I shoved my man away and headed for the surface.
I felt pretty guilty about leaving you with two of them."</p>
<p>Rick returned the grin. "I felt the same way. I thought I'd abandoned
you. But I see you got to the surface first."</p>
<p>Steve accepted a cup of coffee and squatted on the deck, facing them.
"Suppose we start from the beginning. What happened?"</p>
<p>Rick told him, starting from the moment when they had heard the brass
ball wail. He finished, "There were three of them. Did you get them
all?"</p>
<p>"Yes. Including one with a spear through his leg. The last one is just
being hauled aboard now. He tried to get to the island."</p>
<p>Jimmy Kelly and a group of frogmen joined them. Jimmy asked, "How about
the sounding gear, Steve?"</p>
<p>"We'll ask now. How about that octopus cave? Where is it?"</p>
<p>"We'll take you," Rick said. "Let us get tanks from our boat. There
should be a pair fully charged by now."</p>
<p>Steve shot a look at the doctor. The officer shrugged, then nodded.
"Okay, if it's a short dive. They've had plenty for today."</p>
<p>"Chief? Where are you?" Kelly called.</p>
<p>A frogman stepped from the rear of the group. "Here, Sir."</p>
<p>"Check their regulators, please. If they're okay, hook up fresh tanks.
If not, loan them complete outfits."</p>
<p>"Yes, Sir."</p>
<p>"Thanks, Chief. Then get set to come with us. Danny, Jonesy, Mike, and
Dick come along, too. Bring still and motion-picture cameras. When we
get down, split into two-man teams and search the area. You know what
we're looking for. It's just like the one we found off St. Croix."</p>
<p>Rick stared at the frogman officer. Another brass ball off St. Croix?
But there wasn't time for questions.</p>
<p>"Quick dive, please," Zircon requested. "These boys have had enough."</p>
<p>"They're through as soon as they show us the cave," Steve agreed. "Come
on, gang. Let's get to it."</p>
<p>Rick carefully checked his equipment, something that no diver can ever
take for granted or leave to someone else, while Scotty did the same.
Then they put the equipment on and adjusted face masks. Their knives,
Rick's camera, and Scotty's spear and gun were somewhere near the wreck.
They would have to get them another time.</p>
<p>The group entered the water. Rick looked around and oriented himself by
the position of the <i>Water Witch</i>, then led the way with Scotty, Steve,
and Jimmy swimming along with him while the Navy frogmen stayed closed
behind.</p>
<p>It was a thrill for Rick to be swimming with the famous UDT frogmen. He
looked to the side and saw that Steve was perfectly at home in the
water, and he marveled at the adaptability of the JANIG agent. Steve
hadn't been joking when he said he would be an expert by nightfall.</p>
<p>At the reef Rick turned northward and led the way toward the level of
the cave. A few moments later he hooted for attention and with pointed
finger showed it to Steve and Jimmy. The octopus was still there.</p>
<p>A frogman swam over and picked the little creature up. The octopus
spurted away, leaving a blob of ink behind. He came to rest above the
cave, poised for further flight.</p>
<p>Rick swam down to the sandy floor of the cave and began to search for
the brass ball. Scotty beckoned, and they swam together toward the spot
where Scotty had last seen it. The frogmen swam to the bottom with them,
then fanned out, searching.</p>
<p>A few moments later someone hooted, and a tanned, muscled frogman swam
over, holding the object triumphantly.</p>
<p>Steve Ames pointed to the surface and Jimmy hooted an order. The group
swam leisurely up through the murky layer, oriented themselves by the
sleek shape of the destroyer escort hull, and emerged at the landing.
The frogman who had found the ball handed it up to Hobart Zircon.</p>
<p>Steve Ames motioned to one of the frogmen. "Run these fellows over to
the beach, please, then wait and bring them back." He turned to the
boys. "Put on dry clothes. Then come on back. We need to talk."</p>
<p>An hour later the boys, the scientists, Steve, and Kelly were seated at
a table in the destroyer escort's tiny wardroom, noses twitching over
the savory steaks that were being served. The boys ate like starved men,
talking a steady stream between bites.</p>
<p>Rick sighed and let out his belt. "Well, that's our story. What's
yours?"</p>
<p>Steve stirred his coffee thoughtfully. "I can make it short. We don't
know the whole story yet, but we will by the time I get back to St.
Thomas. Have you two any idea what these brass-ball gadgets are?"</p>
<p>"We decided that they were probably sonar equipment of some type,"
Scotty said. "But we couldn't figure out what they were for."</p>
<p>"Easy," Steve said. "Although you couldn't know, of course. They were
for spotting submarines."</p>
<p>Rick stared. Submarines?</p>
<p>Steve saw his look of bewilderment. "It happens that our new
atomic-powered submarines are conducting manuevers in this area. Does
that help?"</p>
<p>It did! Light slowly dawned. "Then these were scanning our subs! But I
still don't see why it would be any problem to find them. The subs must
have equipment that will tell when sonar beams hit them."</p>
<p>"They do. And that's a big part of the story."</p>
<p>Steve sipped his coffee for a moment. "These sonar devices are a new
type, and very cleverly designed. They don't send out a continuous beam.
Instead, they operate in bursts, in a random pattern. They might send
out a beam twice in a minute, or wait an hour between bursts. The beam
is a powerful one. It's effective for an extraordinary distance."</p>
<p>"The wail, of course, was the beam operating," Zircon interjected. "You
didn't hear the beam itself, since that's ultrasonic. But you did hear
the mechanical vibration of the brass ball. It had a kind of
sub-harmonic effect that was audible."</p>
<p>"That's right," Steve agreed. "Anyway, there were several different
stations, in different locations. Some were on islands, some on fishing
boats. Since they operated only in short bursts in a random pattern, the
subs—and the special teams we sent out—were never able to get a
bearing that meant much."</p>
<p>"They must be self-recording," Rick said thoughtfully, "otherwise the
enemy couldn't get the information out of them."</p>
<p>"They are. Whatever echo they get makes a tracing inside the box they're
mounted on."</p>
<p>Scotty objected, "But what kind of information is it? How can anyone
tell anything about the subs from such recordings?"</p>
<p>"By putting all the recordings together and running a rather complex
analysis. The analysis will give speed, depth of operation,
maneuverability—if the spies are lucky to have beams operating at the
right time—and number of torpedoes fired, with the same information on
the torps. That's enough information to make it worth an enemy's while."</p>
<p>"I'll say!" Scotty turned to Zircon. "And what were you doing,
Professor?"</p>
<p>"I'm afraid I arrived on the scene too late to do much good," Zircon
boomed. "However, I believe we can be useful in preventing such
occurrences in the future. I have an idea for an improvement in our
scanners that will allow a fix to be made on such beams."</p>
<p>There was a pause when dessert arrived. The boys savored excellent apple
pie smothered in a generous helping of ship-made ice cream.</p>
<p>"We thought Zircon might help us work out a system of getting fixes on
the transmitters," Steve said. "As it happened, we got a lucky break.
The subs happened to have their devices pointed at St. Croix
simultaneously when a beam scanned them. They got a fix on it. We flew a
team of frogmen down in a Navy amphibian right in the middle of the
second storm. They found it, and got the men who were handling it. One
of them talked."</p>
<p>Jimmy Kelly picked up the story, "You arrived with Zircon at about the
same time the St. Croix team took off from our base, and headed right
into the storm. They didn't get back until late last night, and it was
nearly dawn before we got the story from the man who talked. Then we
loaded on this DE and headed here."</p>
<p>"I'm glad you didn't wait ten minutes longer," Rick said fervently.
"They foxed us. I kept listening for their boat, but they didn't use
it."</p>
<p>"They probably decided to swim out and sneak up on you," Zircon stated.
"After capturing Tony last night, their suspicions were probably aroused
somewhat. Even if they swallowed his story entirely, it would be only
good sense to check up."</p>
<p>Tony looked hurt. "I'm sorry you don't think my story was enough to
allay their suspicions entirely. But speaking of listening for their
boat, why didn't you hear this ship coming? And why didn't the fancy
frogmen?"</p>
<p>Rick thought that one over. "We wouldn't have heard the ship until it
was very close because of the noise our bubbles make. But we should have
heard it about the time it left the reef opening near our cottage. I
don't know why we didn't."</p>
<p>"And I don't know why we didn't see it," Scotty added. "It's big enough
to be spotted at horizon distance."</p>
<p>Jimmy grinned. "We pulled a fast one. We had enough steerageway to drift
over your position after a few turns of the screws down by the reef
passage. You see, we didn't know what was going on, so we took no
chances. Then, when we got into position, we got into the water without
waiting to anchor. We dropped anchor right after we got both of you out,
but you probably didn't notice."</p>
<p>"I couldn't have cared less, at that point," Rick said, and Scotty
echoed the sentiment.</p>
<p>"The reason why you didn't see us coming is that we came from the other
side of the island. It's safer for a ship that draws as much water as
this one. Tony spotted us as we approached the southern point."</p>
<p>Steve grinned. "Anyway, it's a good idea to move in on an objective as
quickly, silently, and invisibly as possible."</p>
<p>"Have you captured the rest of the stations yet?" Rick asked.</p>
<p>"No. But we have teams out, and they know where to go and what to look
for, thanks to the man who talked last night."</p>
<p>"Who are these people?" Scotty demanded.</p>
<p>Steve scratched his chin. "Well," he said finally, "you might put it
this way: they're people who have no business knowing what they're
trying to find out."</p>
<p>Rick hid a grin. He knew perfectly well they would get no more
information out of Steve. The essence of security is to give information
only to people who have a need to know it. The Spindrifters had no
reason for knowing the identity of the enemy, apart from their own
curiosity. One thing was certain, though, it was another nation that
wanted the information.</p>
<p>"You're probably tired of answering questions," Rick said, "but I've got
one more. How did you happen to arrive right in the nick of time?"</p>
<p>"Nothing very mysterious about it," Jimmy Kelly answered. "We steamed up
to the island and sent a boat ashore, with Professor Zircon. Dr. Briotti
had seen us approach, and he met the boat. He told us you were diving.
Zircon had assumed as much since we could see your boat anchored on the
reef."</p>
<p>"I told them about last night," Tony added.</p>
<p>"Yes, and we sent a party of men to the house up the beach to capture
these fancy frogmen of yours. The house was empty. Since their boat was
tied up, we made a quick assumption that they were out on the reef with
you. We did a fast run out ..."</p>
<p>"And got the fright of our lives," Steve finished. "We knew there were
three of the enemy and two of you down below, and we could see only
three sets of bubbles. We thought you were done for."</p>
<p>"It was remarkable the way Lieutenant Kelly and his men got ready to
dive," Zircon said. "I've never seen people move so fast. Steve, too.
Then, just as they were about to go over the side, we saw two more
bubble trails and knew at least that you were still alive. But in a
moment the entire pack of bubbles merged."</p>
<p>"We hit the water," Jimmy Kelly said, "and were about to dive when one
of the enemy skyrocketed up. He was blue in the face and scared witless.
We hauled him out and then started to dive again. And along came Scotty,
half dead and babbling about you. I started straight down to get you,
but you met me halfway." He grinned. "You weren't in very good shape,
either, for a few minutes."</p>
<p>"How about the men? Where are they?" Scotty asked.</p>
<p>"Down below. Locked up, with an armed guard at the door."</p>
<p>Steve Ames finished his coffee and sat back with a sigh of satisfaction.
"I'm happy," he announced.</p>
<p>The boys grinned. He looked it.</p>
<p>"Glad you wound this up so fast," Zircon boomed. "When will you return
to Charlotte Amalie?"</p>
<p>Steve looked at Jimmy Kelly. "You in a hurry?"</p>
<p>"Not particularly. Now that this case is over we go back to some pretty
dull routine. Why?"</p>
<p>"Oh, I thought your boys might like a little recreation."</p>
<p>Jimmy looked suspicious. "Any sailor likes recreation. The more the
better. The UDTs enjoy it more than most. What's on your mind?"</p>
<p>Steve's wave took in the four Spindrifters. "It wasn't their fault one
of the gang talked his head off last night. If he hadn't, their work
here would have given us a lead we couldn't have gotten in any other
way. Suppose we repay 'em."</p>
<p>Jimmy sighed. "Get to the point."</p>
<p>"Keep the ship here tomorrow. Turn your boys loose to help find the
treasure they're after. You've got equipment they need. Besides, I'm
sure your gang can find some nice souvenirs if they put their minds to
it. Old cutlasses, cannon, cannon balls—things like that."</p>
<p>"It's a deal." The UDT lieutenant chuckled. "I'll try a little souvenir
hunting myself. Of course, since it's unofficial, I'll have to ask for
volunteers."</p>
<p>"Think you'll get many?" Rick asked anxiously.</p>
<p>Steve and Jimmy laughed. The lieutenant said with a chuckle, "If one of
them doesn't volunteer I'll turn him over to the doctor, because I'll
know he's sick. The UDT's volunteer because they like to swim. It isn't
often they get a chance like this, to dive just for fun."</p>
<p>"If we don't find the treasure," Scotty said with satisfaction, "it'll
be because it isn't there!"</p>
